How do I skip a loop with pdb?

How can I skip over a loop using pdb.set_trace()?

For example,

pdb.set_trace()
for i in range(5):
     print(i)

print('Done!')

pdb prompts before the loop. I input a command. All 1-5 values are returned and then I'd like to be prompted with pdb again before the print('Done!') executes.

Try the until statement.

Go to the last line of the loop (with next or n) and then use until or unt. This will take you to the next line, right after the loop.

http://www.doughellmann.com/PyMOTW/pdb/ has a good explanation

In the link mentioned by the accepted answer (https://pymotw.com/3/pdb/), I found this section somewhat more helpful:

To let execution run until a specific line, pass the line number to the until command.

Here's an example of how that can work re: loops:

It spares you from two things: having to create extra breakpoints, and having to navigate to the end of a loop (especially when you might have already iterated such that you wouldn't be able to without re-running the debugger).

Here's the Python docs on until. Btw I'm using pdb++ as a drop-in for the standard debugger (hence the formatting) but until works the same in both.

You can set another breakpoint after the loop and jump to it (when debugging) with c:

pdb.set_trace()
for i in range(5):
    print(i)

pdb.set_trace()
print('Done!')
